How to mount pedal assembly

[SwissCuda]

There are 8 holes in the firewall for the pedal assembly / power brake unit. I am not sure if all are used.

I am not sure if I should mount the pedals assembly first and the power brake unit after of mount the power brake in a way that it retains the pedals assembly

Can somebody explain or send pictures?

Many thanks

they mount differently depending if you have power or manual brakes , the brace mount up to the cowl & through the firewall & the pedals mount to the brace

Here is a picture of the brace that Neil mentioned.

Found this video that might help you. It's a bit annoying but explains it.

The four yellow ovals in your picture are for power brakes, four green standard brakes.
I usually mount the pedals first, using an awl to keep the firewall holes lined up while I tighten the pedals.
Another tip is to put the power brake lever system on the booster first before fitting it on to the firewall.

Peddles first.
